Fiol is a traditional Swedish string instrument, similar to a violin but typically larger and with a deeper sound. It is often used in folk music and is characterized by its unique shape and construction, which can vary by region. The instrument is played with a bow and has four strings, producing a rich, resonant tone that is integral to many Swedish cultural celebrations. The fiol has a long history in Sweden, dating back to the 16th century, and is closely associated with Swedish folk music. Musicians often play the fiol in ensembles, alongside other instruments like the nyckelharpa and accordion, creating lively and engaging performances that reflect the country's musical heritage.
